autoflower grow

Learn to grow autoflowering cannabis.

After you’ve prepared the mix, add some Easy Boost Organic Nutrition to the blend. These pellets will slowly release adequate levels of nutrition into the soil, providing foundational elements and minerals for the entire growing cycle. Add some mycorrhiza to the soil to help your plants flourish later down the line. These symbiotic fungi will bind to the root system and help your plants uptake nutrients more effectively.

HOW LONG DO AUTOFLOWERS TAKE FROM SEED TO HARVEST?

Next, poke a 10–15mm hole into a pot with your soil mix. Sow your seed directly into its final pot to avoid the stress of repotting later down the line. Transplanting causes plants to go into shock, and autoflowers grow so fast that they’ll struggle to recover. Place a seed in the hole and cover lightly with soil. You’ll see your seedling emerge in the next few days.

As the name suggests, autoflowering strains don’t require a change in the light cycle to enter the flowering stage. Many growers choose to keep their autoflowers on a light schedule of 18 hours on and 6 hours off during the entire growing cycle. Other cultivators choose to keep their lights on around the clock in hopes of maximising photosynthesis and growth rate, however, this can get quite expensive.

Germination usually takes 1–3 days. During this time, your seeds will activate and send a root down into the soil and a shoot above the surface. To begin the germination process, you’ll need to prepare a suitable soil mix. Autoflowers don’t need as much nutrients as photoperiod varieties and prefer light and airy soil.

Most autoflowers reach a height of around 50-100cm but a plant’s size depends on the genetics and growing conditions. Also, all strains are different so you will find Sativa and Indica-leaning autos; Most Indica hybrid autoflowers will stay around the 80-120cm mark but Sativa-dominant autoflowers can reach up to 175cm tall.

Despite having to keep the seeds in damp paper towels, make sure they are not completely wet, too much water can rot the seeds. The best way to identify this is by smell if the paper towels start to smell like mold, immediately take them out and change the towels.

This solely depends on your climate, you need to remember that autos prefer dry sunny days so if you’re planning to have just one grow cycle, you can start them 1-2 weeks into Summer, and if you’re planning to have 2 harvests, start the next one right after finishing the first one.

Macro and micronutrients

Frost must be avoided at all costs. Typically, most growers begin planting when spring is just around the corner. Depending on where you live, you can plant the seeds as soon as the frost clears. If you reside in a location that doesn’t receive any snow, go ahead and plant when the temperatures range between 22°C to 28°C (71°F to 77°F).

What’s the average autoflower size and how tall can they get?

Bigger autoflowers need bigger containers, so make sure you check the description before purchasing seeds. Root aeration is often overlooked, but it’s an important factor in determining your yields.

How long will it take for my auto to start flowering?

The most important thing to remember with autos is to avoid using any plant training method that involves cutting the plant. When reading about cannabis training techniques that involve cutting the plant such as topping, FIMing, or main-lining, please remember that these techniques were developed for photoperiod plants and are not well-suited to auto-flowering strains.

It’s important to note that some photoperiod strains grow in the same way, and I don’t believe that extra leaves during the budding process is necessarily a bad thing. If anything, the extra leaves seem to power the growth of buds, causing them to swell up more in a smaller amount of time and less light that photoperiod strains.

However, one major difference is that many auto-flowering strains tend to have higher amounts of CBD in their buds than photoperiod strains (because Ruderalis plants are high-CBD). CBD is a cannabinoid that is known for having medical properties as well as reducing anxiety.

On the flip side, if your grow doesn’t go as well as planned, at least it will be harvest time in just 2-3 months, you’ll learn a lot, and you’ll have the opportunity to try again. That being said, autos are essentially very simple and a first-time grower can easily get a great harvest on their very first grow. Plus, auto-flowering plants (and cannabis plants in general) are hardy! As long as you give them basic care, they will reward you!

Auto-Flowering Strains

For an auto-flowering cannabis plant, a grower doesn’t have to worry about light schedules. Each auto-flowering plant starts blooming after a few weeks no matter what light schedule is provided. For outdoor auto growers, there’s no need to match up the strain with your local time zone or plant at the perfect time – simply plant autos when you know you have at least 2-3 months of warm, sunny weather.

Whether you grow in soil, coco coir, or a full hydroponic setup, auto plants tend to prefer relatively low levels of nutrients compared to many other cannabis strains.
